# Edit an AI prompt version in place (internal)

**PATCH /ai/admin/prompts/{purpose}/versions/{versionSlug}**

Edits the system prompt, tool description or input schema, model, token limit, temperature or notes of a version without changing its `versionSlug`, so meant for small fixes; use a new draft for material changes. Renaming or removing top-level tool input properties returns 400; an unknown version returns 404. An unknown `purpose` returns 400. Super admins only.
